3 Proof of Concept Stage (POC) POC is a smaller scale synchrophasor system used to test, validate, and demonstrate various functions, interoperability before field deployment. Also: Serves as a trouble shooting platform throughout the project Helps address life cycle support questions and requirements Provide initial training grounds for various disciplines Helps drive solutions both internal and the global standards (e.g: IEEE and IEC) POC system includes: Minimum of 8 s, 2 Aggregate PDCs, 2 Super PDCs (and EMS systems) A Emulator (Generates over 40 at 120 phasors/s, each stream 12 values) Digital Fault Recorder (DFR) and testing for PRC-002 recording Real Time Digital Simulation (RTDS) system COMTRADE file playback system GPS Clock with IRIG-B and IEEE-1588 time distribution protocols Additional series of test equipment capable of generating time-synched analog and digital signals Five 3-phase voltage Sources Ten 3-phase current sources Synchronized test waveform generation Noise impairment Tools ologyand Tec Communication routers, switches, delay line, as well as test equipment (e.g., traffic and error bit generators) Testing is well underway with significant results 2

7 and PDC Initial Key Test Considerations Port set-up and data framing / packets True transparent multicasting Data streaming - Records per second set point, and performance when multi-functions are assigned to the port E.g: Protection functions vs. Synchrophasor data streaming Threshold set points for PDC processing Ramp and step responses PDC performance Impact of noise or data streaming impairment data with momentary loss of synchronization Data reporting for different Classes of data ( P and M ) Bandwidth and storage verification 6

8 TCP / UDP Communication Observations -2 Various combination of TCP/UDP protocols are available in products for communicating commands (from PDC to ), header and configuration files (from to PDC), and data streams (to PDC). IP Combinations Command (from PDC to CFG / HEADER Phasor Data Available ) OPT-1 (Ignored) UDP (periodic, UDP unsolicited) OPT-2 TCP TCP UDP OPT-3 TCP UDP UDP OPT-4 TCP TCP TCP

9 POC Observations Continued - Various set up and product interoperability Verify various combinations of UDP and TCP protocols used in each product for Command communications (e.g., start/stop) Configuration communications (e.g., Config 1, Config2, and future Connfig 3) Synchrophasor data streaming Verify Config files (Config 1, 2, and 3) Certain s expect control bits in the IRIG clock to be set to send correct year. Without these, they use default year (2000). Other s can use the IRIG clock without the control bits, and the use a local device clock setting as the date / year etc. From end user perspective, the UTC time: Should be transparent relative to the local time displayed in front of the clock Real-time information should be in local time COMTRADE file plots and other post mortem troubleshooting tools need to display in lcoal time with optional user conversion tool for UTC time. 8

12 Noise Impairment Test Dropped Data Packets - Noise Impairment tests Missing/corrupted data packets The PDC interpolated for the missing / corrupt data packets Used a logarithmic signal pattern to test - network corrupting 1 phasor packet for every 13 packets PDC Interpolates to replace missing data PDC is required to flag data is interpolated Ideal Uncorrupted signal Output of PDC (Interpolated when data missing) 11

13 Noise Impairment Test Corrupt Data Injection - Noise Impairment tests Frequent corrupt data packets Data frame withheld and sent much later (20 frames later) 12

14 Additional points - GOOSE message triggering Use of GOOSE messaging The devices are programmed to perform a data record capture on receipt of a message Adaptive protection application and visualization applications (DOE research project) DOE Research Grant - Power Cycle Testing Verify devices and aggregate PDCs able to re-establish connection on power cycling of individual devices. Power cycling certain devices did not result in re-establishment of connection (these s happen to use TCP connection). The PDC had to be restarted for the connection to be established again. - Measurements reported on low magnitudes Some s may zero out reported angles, when the magnitude is too low. Other s may report whatever their calculations show (usually random variation of angles if magnitude is zero.) Various set up and product interoperability verifications Have seen variations among measurements (within TVE of 1%) 13
